BACKGROUND OF THE INVENTION

A. Field of the Invention

The present invention relates to a building foundation method formodular homes.

B. Discussion of Related Art

Traditional methods of making foundation in modular and manufacturedhomes have been inefficient and have damaged many homes causing loss toinsurers and unnecessary environmental degradation because of demolitionwaste. If a modular house slips off its foundation, the house generallybecomes uninhabitable and usually has to be demolished because of thefoundation damage. This can cause a total loss of all time and effortand materials that were invested into the building. The old methods alsowaste time and material because redundant permanent foundation must bebuilt to support the building of more permanent foundation. A variety ofinventors have attempted to make structurally sound manufactured homeswithout material waste.

Manufactured homes are typically transported to a customer's site for apermanent or semi-permanent setup. One way to make a foundation is tocast an on the ground building foundation in the form of concrete piersto support the complete building while vertical supports such asconstruction piers and stanchions at selected locations in thefoundation plan are engaged at their top ends to an undercarriage of thebuilding and their bottom ends are buried in fabric containers ofcementations slurry until the piers and stanchions become an integralfoundation in the solid block of concrete conformed to the ground forthe leveled dwelling house. This method developed by inventor Art Angelois related to the anchor panel method described by Michael Butler inU.S. Pat. No. 5,564,235 entitled Foundation and Floor ConstructionMeans. Butler in U.S. Pat. No. 6,076,320 entitled Foundation for aModular Structure, and Butler in U.S. Pat. No. 6,205,725 entitledInterlocking Corrugated Panel Wall Cast In-Situ are all variations onthe anchor panel method.

The foundation structure in the Butler references teaches use of on siteconcrete piers supporting a truss having a periphery bounded bycorrugated metal panels that define a periphery of a concretefoundation. The use of concrete piers in either case is burdensome andincreases the set up time. The further use of the panels increases theset up time even more, even though the panels may have a decorativeeffect. The necessity of cast-in-place and on-the-ground buildingfoundations is redundant and adds time to setup and should be avoided.The best case situation is when the periphery foundation can be set atthe same time as the foundation in the center of the house.

There are various support designs for building suspension. U.S. Pat. No.4,348,843 discloses height-adjustable I-Beam stanchions for supportingthe I-Beam bearing the mobile home undercarriage. The stanchion has twoangle iron support arms extending from the bottom of the stanchion atright angle to each other reaching the undercarriage to assist insupporting the I-Beam and undercarriage.

U.S. Pat. No. 5,727,767 offers a mobile home support stand forpermanently supporting a mobile home to counteract high winds and/orearth vibrations. The support stand has a support stud functioning as ascrew-jack disposed between a ground steel post and a home I beam, and ahold down assembly clamps the post and beam together. Using these andother known structures was slow because ten or more vertical supportpiers were necessary for each undercarriage joist or I beam and thetotal number of piers is multiplied by the manufactured home size.

SUMMARY OF THE INVENTION

This improved method of forming a foundation uses a dynamic levelingfoundation and method uses a prelevel coplanar support while installingpermanent foundation. This improved method starts when a manufacturedhouse arrives at the permanent site. The manufactured house has flooringassembly supported on its underside by horizontal parallel beams orjoists that needs firmly grounded foundation support.

The temporary support step provides a temporary level support for themanufactured house. When the temporary support is established, the housearrives from the factory. The preferred temporary support is a temporarytripod support system that may be installed under the sidewalls and themate line. The tripod support system comprises multiple tripods eachhaving a triangular transverse frame to support an extendedundercarriage area. Due to its triangle top, each tripod makes at leasttwo separate supporting abutments with its overlying perimeter joist ormate line joist which reduces total labor time required.

The buttress attachment step is after the temporary support step.Buttress assemblies are attached to the perimeter joist and mate linejoist. The preferred buttress assembly is a tubular stanchion having anupper and lower end, an anchor base plate welded to the lower end of thestanchion and transverse tabs attached to the intermediate portion ofthe stanchion. Buttress assemblies hang in the air awaiting rebar. Rebaris then shaped around and hung on uplift bars that protrude from thebottom of the base plate and act as hooks to suspend the rebar. Theuplift bars center the rebar allowing superior strength.

The fabric container is unfurled from a package so that it forms asleeve and rests on the ground. A porous fabric container has inletholes to receive concrete slurry and is attached to each buttressassembly member. Fabric sleeve corners form rectangular corners and canbe joined to the straight sections of fabric sleeve.

The foundation pouring step involves pouring the concrete into thefoundation sleeve. The concrete foundation material envelopes the bottomof the buttress assembly and conforms to the fabric sleeve which lies onthe ground. The foundation sets with the enveloped portion of thebuttress assembly embedded forming a direct support from the buttressassembly to the rebar reinforced concrete foundation, to the ground.

The tabs also called wings on the buttress support then receive ametallic backfill plate. A cement board is attached over the backfillplate. Stucco or other finish can be installed over the cement board. Aventilation screen covers a ventilation gap between the cement board andthe rim joist. The final installation is a belly band which is acircumferential siding attached to the perimeter rim joist. The bellyband has clearance between the stucco and the rim joist providing acircumferential and continuous ventilation. The cross ventilation allowsairflow under the house and prevents black mold infestation. Afterbackfill soil is put against the stucco attached to the cement board,the house is indistinguishable from an on site built house.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

This improved method of forming a foundation uses a temporary prelevelcoplanar support while installing a dynamic leveling permanentfoundation. This improved method starts when a manufactured housearrives at the permanent site. The manufactured house has flooringassembly supported on its underside by horizontal parallel beams orjoists that needs firmly grounded foundation support. The modular housemay be a pair of elongated sections brought to the construction site bya truck. Preferably, the width of each module can fit on a singleflatbed truck. The sections of the modular house are placed upontemporary supports by a crane and leveled. The buttress assemblies 210arrive at the job site fully assembled and welded including the tubularstanchion 212, L-shaped bracket 211, vertical flange 214, base plate217, anchor bolt head 218 or J shaped uplift bars, and steel tabs 219.Each of the sections of the modular house is joined to the others.Underneath the house the mate line piers 234 are attached to mate linejoists 233. The improved buttress assembly 210 is installed to theperimeter joist so that the tubular stanchion 212 having at its top anL-shaped bracket 211 abuts the perimeter joist 322 at a perimeter joistbottom plane 323 and a perimeter joist inside plane 224. The fabriccontainer 201 is unfurled allowing pouring of the concrete portion 206into the fabric container 201. After the concrete portion 206 cures, themodular house temporary support is removed.

Temporary Support Step

The first step is the temporary support step that provides a temporarylevel support for the manufactured house. The preferred temporarysupport is a temporary tripod support system that may be installed underthe sidewalls and the mate line. The temporary prelevel coplanar supportis preferably embodied as a truss tripod unit 10, though each trusstripod unit could optionally have additional legs such that the totalnumber of legs is more than three. Referring to FIGS. 1 and 2, a tripodsupport 10 is shown assembled to buttress the bottom of a sidewall ofhome 11. The tripod support 10 has three identical piers of which piers12 and 13 are numbered in FIG. 2. The pier 12 comprises four metal legs15 through 18 welded to a rectangular bottom frame 19, which is in turnfastened by nails or screws to a bearing pad 20 laid on the ground. Thepad 20 may be made of wood. The legs 15-18 are converged at their upperends where they are welded together. At the top of the legs a stoppernut 21 is rotatably installed. The nut 21 is positioned so that itsinner threads extend vertically in the center of the pier 12.

The tripod support system comprises multiple tripods each having atriangular transverse frame to support an extended undercarriage area.Due to its triangle top, each tripod makes at least two separatesupporting abutments with its overlying perimeter joist or mate linejoist which reduces total labor time required. Triangular framework 22of three cross beams 22 a, 22 b and 22 c are suspended to make contactwith the sidewall 11. This suspension is enforced by three saddlemembers 23 adjustably threaded to the nut 21 of the pier 12 through arod 24 which has corresponding threads formed on its outer faces and iswelded to the bottom of the saddle member 23 as shown in detail in FIG.3. Thus, the saddle member 23, threaded rod 24 and nut 21 togetherconstitute a saddle jack assembly 25 for buttressing the cross beams 22a-22 c at their junctions.

Referring further to FIG. 4, the saddle member 23 with rod 24 of thesaddle jack assembly 25 is adapted to be transported as a loosecomponent to the construction site where it is assembled with the crossbeams as well as the corresponding pier.

The cross beams 22 a-22 c have a common structure so that they can beinterchangeably laid to extend between any two saddle jack assemblies 25forming the triangular framework 22. In a right handed configuration,the four walls cooperate, two of them holding a right supporting beamand two of them holding a left supporting beam. The right supportingbeam extends beyond the end of the left supporting beam. Because theyare identical, the beams can be interchanged, and the saddle jacks canalso be interchanged. The top of view of the saddle jack shows that theconfiguration can be reversed so that the left beam protrudes beyond theend of the right beam, so that the top view is a mirror image. Taking amirror image configuration translates a right handed configuration intoa left handed configuration.

The saddle member 23 has a horizontal plate 26 comprising an elongatedmain plate section 27 and a crossing plate section 28 extending from themain plate section so that the longitudinal axis of the section 27 andan extension of the longitudinal axis of the section 28 meet at an angleA of about 60°. In addition, the crossing plate section 28 has two endwalls of which a shorter wall 29 stands upright from a shorter lateralend of the plate section 28 facing clockwise direction in FIGS. 2 and 4and a longer wall 30 stands upright from a longer lateral end at theother side. The opposing walls 29 and 30 may have a third bridging wallbetween them as shown in FIG. 2 to limit the cross beam 22 a in itslongitudinal movements although an open structure of FIG. 4 works wellto hold the beam.

On the other hand, the main plate section 27 has a first end wall 31extending along the entire lateral edge of the plate section 27 facingapproximately the same direction of the shorter end wall 29 of the platesection 28. The first end wall 31 also joins the shorter end wall 29 atan inner merging point 32 between the plate sections 28 and 28.

However, at the other side of the first end wall 31 the main platesection 27 has a second end wall 33 extending from an open end 34 of themain section 27 and terminating short of a virtual extension line of theshorter end wall 29 to allow for laying the cross beam 22 a past thesecond end wall 33. The second end wall 33 faces inwardly of thetriangular framework 22 in FIG. 2. The threaded rod 24 may be centeredalong a line connecting the inner merging point 32 and an outer mergingpoint 35.

The cross beams 22 a and 22 b are shown as seated in the saddle jackassembly 25 making an angled joint of the beams each having rectangularcross sections. The beam 22 a has a first blunt end 36 adapted to beseated on the saddle member 23 defined by the plate section 28 and theopposing walls 29 and 30. The other second end of the beam 22 a is notshown in FIG. 4 but is similar to the next cross beam 22 b wherein itsabutment end 37 is cut at the angle A to make an angled assemblage withthe opposing side of the blunt end 36 of the cross beam 22 a when thecross beam 22 b is seated on the saddle member 23 defined by the platesection 27 and the opposing walls 31 and 33.

The saddle jack has an interior connection and an exterior connection.The interior connection has a portion of the connection inside of thetriangle formed by the horizontal supporting beams, and the exteriorconnection is located outside of the triangle formed by the horizontalsupporting beams. The first connection is the interior connection shownin FIG. 4 as a bolted connection 44, 45. The exterior connection is alsoshown as a bolted connection 40, 41. Assembling the blunt end 36 of thecross beam 22 a with the saddle jack assembly 25 may be done by using athru bolt 40 and a nut 41 threaded through an opening 42 in the end wall29 and an opening 43 in the end wall 30. Likewise, the mating abutmentend 37 of the cross beam 22 b may be assembled with the saddle jackassembly 25 using a thru bolt 44 and a nut 45 threaded through anopening 46 in the end wall 31 and an opening 47 in the end wall 33.Optionally, washers 48 may be used with these fastening members.

FIG. 5 shows the tripod support system of the present invention appliedto the manufactured home 11 on site. The home 11 has been suspended bythe tripod support system of the present invention in which two ofseveral tripod supports for the visible sidewall are demonstrating theactual field installations.

During the operation of the tripod supports, a ground surfacecast-in-place foundation assembly 100 is made with a plurality ofbuttress assemblies 101 set in the foundation to vertically engage theperimeter beam of the level modular home 11. When the home foundation100 is solidified, the tripod supports 10 may be easily retrieved byfirst turning a round of the stopper nuts 21 to lower the saddle jackassemblies 25 out of engagements with the home 11. The released tripodsupports 10 can be immediately disassembled at their joints byunscrewing the nuts 41 and 45 of the saddle jack assemblies 25 intosmall and easy parts to transport to the next construction site. Thenuts can be tightened against the pier, as seen in figure one, allowingthe vertical and rotational retention of the saddle jack. The nuts canalso be called locking nuts.

Buttress Attachment Step

The buttress attachment step is after the temporary support step.Buttress assemblies are attached to the perimeter joist and mate linejoist. The preferred buttress assembly is a tubular stanchion having anupper and lower end, an anchor base plate welded to the lower end of thestanchion and transverse tabs attached to the intermediate portion ofthe stanchion. Buttress assemblies hang in the air awaiting rebar. Rebaris then shaped around and hung on uplift bars that protrude from thebottom of the base plate and act as hooks to position the suspendedrebar. The anchor bolts are formed as bent metal hooks that form upliftbars that center the rebar allowing superior foundation strength.Alternatively, uplift bars can be welded on instead of anchor bolted.

Referring to FIG. 6, the novel and improved buttress assembly 210 iscomprised of a selected length of tubular stanchion 212 having at itstop an L-shaped bracket 211 to abut the perimeter joist 222 at itsbottom plane 223 and an inside plane 224. The stanchion 212 has fourside walls and a rectangular cross section. The L-shaped bracket 211 hasa vertical flange 214 with a number of apertures through which attachinguplift bars 215 are threaded into the interior side of the joist 222such that the base portion of the stanchion 212 is suspended severalinches above ground surface 216. In conformance to current technology,it is appreciated that stanchion 212, bracket 214, base plate 217,anchor heads 218, girt 220 and uplift bars 215 and 221 of this inventionbe constructed of iron, steel, cast aluminum or other appropriatelyrigid material.

A base plate 217 is welded to the base portion of the stanchion 212. Onthe bottom of the base plate 217 a number of anchor bolt heads 218 areprotruded downwardly. Alternatively, J-shaped uplift bars can alsoreplace the straight uplift bars 218. On a wall of the stanchion 212away from the vertical flange 214 two steel tabs 219 are weldedintermediately with a longitudinal distance from each other to hold agirt 220.

Fabric Container Attachment Step

Fabric container 201 is placed beneath the stanchion 212 and while thebottom end of the container 201 resides on the ground surface 216, arebar 202 is inserted into the container 201 and the entrance tocontainer 201 is suitably tied around stanchion 212, concrete slurry 6is poured into container 201 to its full capacity. The three dimensionalshape of the base plate 217 with anchor heads 218 will also provide anexceptional holding force in the resulting concrete base 206 of thebuttress foundation 210.

Thus, the buttress foundation 210 has been completed for the overlyingstructure of the perimeter joist 222 upon which the floor assembly 225and building walls 226 are rested as shown in the drawings. Attached tothe building walls 226 covering the joist 222, an exterior siding 227protects the building against elements. As described above, the girt 220is attached to the stanchion 212 at its steel tabs 219 by the attachingscrews 221 from the exterior side of the girt 220. An elongated board228 is then applied to the girt 220. Then, an elongated strip or trim229 is attached to the bottom edge of the siding 227 covering the topedge of the elongated board 228. The mounting location of the elongatedstrip or trim 229 optionally allows a concealed air gap vent formedbetween the trim 229 and the elongated board 228.

FIG. 8 shows the manufactured home in two parts each having the junctionbetween the home parts, i.e. the mate line 232 is defined by a couple ofmate line joists 222 and suspended by mate line piers 230. The buttressassemblies 210 with the concrete portion 206 and fabric container 201provide a perimeter support embodiment. The fabric container is formedas an elongated sleeve that is wrapped and installed around the buttressassemblies 210 allowing the concrete portion 206 to form a perimeterfoundation that connects all of the buttress assemblies 210 in a singlepiece of concrete. The elongated fabric sleeve can be stored as a rollso that it can be cut to length on the job site. Also, the elongatedfabric sleeve can be a continuous sleeve having no opening, allowing theopenings to be cut at the job site.

The fabric container is unfurled from a package so that it forms asleeve and rests on the ground. A porous fabric container has inletholes to receive concrete slurry and is attached to each buttressassembly member. Fabric sleeve corners form rectangular corners and canbe joined to the straight sections of fabric sleeve. Fabric container201 is composed of any one of the many textile materials well known inthe art.

Foundation Pouring Step

The foundation pouring step involves pouring the concrete into thefoundation sleeve. The concrete foundation material envelopes the bottomof the buttress assembly and conforms to the fabric sleeve which lies onthe ground. The foundation sets with the enveloped portion of thebuttress assembly embedded forming a direct support from the buttressassembly to the rebar reinforced concrete foundation, to the ground.After the concrete foundation step, the concrete sets and the exteriorsiding step begins.

Exterior Siding Step

In the exterior siding step the house receives installation of exteriorsiding 227 such as stucco and elongated board 228. Later, an appropriatefinish such as stucco can be applied to the board 228 so that when theperimeter of the house receives landscape backfill, the backfill willcover a portion of the board 228.

The tabs also called wings on the buttress support then receive a metalbackfill plate 228 shaped as an elongated board. The elongated board 228of the present invention may be of metal, treated plywood or other waterresistant material. A cement board is attached over the backfill plate.Stucco or other finish can be installed over the cement board. Aventilation screen covers a ventilation gap between the cement board andthe rim joist. The final installation is a belly band which is acircumferential siding attached to the perimeter rim joist. The bellyband has clearance between the stucco and the rim joist providing acircumferential and continuous ventilation. The cross ventilation allowsairflow under the house and prevents black mold infestation. Afterbackfill soil is put against the stucco attached to the cement board,the house is indistinguishable from an on site built house.

Therefore, while the presently preferred form of the system and methodhas been shown and described, and several modifications thereofdiscussed, persons skilled in this art will readily appreciate thatvarious additional changes and modifications may be made withoutdeparting from the spirit of the invention, as defined anddifferentiated by the following claims.
